If you can commit sufficient time to understand your results, a flexible insulin therapy can help you to achieve strong blood glucose results.

What are the disadvantages of a flexible insulin routine?

One disadvantage of a flexible insulin regimen is that it can make understanding variations in blood glucose results more difficult as there will be less consistency over carbohydrate intake and insulin dosages.

As noted above, a flexible insulin regimen will most likely need more time to be put into understanding blood glucose results and requires care to be taken in estimating insulin doses.
